it is six times faster than its predecessor but uses only 1/6 of the energy. despite its size and power, it is still love the world's fastest supercomputer. developers, however, say they aspire to be sustainable rather than the world's no. 1 -- it is still not the world's fastest supercomputer. >> it is already being put to use in a new research undertaking -- the human brain project. this brings together some of europe's top scientists, including brain specialists, doctors, computer scientists, physicists, and mathematicians. they are trying to use the super computer to simulate the entire human brain from individual cells to large, complex areas of the brain. >> the project is expected to take 10 years. >> the human brain is extremely complex. there are 100 billion neurons, and about the same number of what are known as galena cells, which help the neurons function. we want to map the entire network correctly and then try to understand how they work. today, not even the most powerful computers are up to this task. >> scientists are eager to analyze different
